Abstract

This study investigates the impact of smartphone usage duration on academic performance and spectacle use among adolescents. A cross-sectional research design was employed, involving 140 adolescents aged 12–18 years, recruited from schools and coaching institutes. The study used stratified random sampling to ensure representation across different socio-economic backgrounds, genders, and urban/rural settings. Participants who owned and used smartphones daily for academic or non-academic purposes were included, while those with pre-existing vision problems unrelated to smartphone use or diagnosed learning disabilities were excluded. The results indicated a modest negative correlation between smartphone usage duration and academic performance, suggesting that prolonged smartphone use may slightly impair academic outcomes. However, no significant correlation was found between smartphone usage and spectacle use. These findings highlight the need for further research into the potential effects of smartphone use on adolescent development, particularly in relation to academic achievement and eye health.
